4-states state machine for CSV parsing

Parsing CSV file is easy, it's nothing but splitting string with comma delimiter, which can be easily done in Java...

Now, reality is that following examples are all possible valid lines in a CSV file 1,Bender 2,"Bender" 3,"Bender, Bending" 4,"Ben""d""er" 5, Ben"der 6, Ben""der Line 7 might be arguable but anyway, two basic rules are If there's comma in field, use double quot to wrap field, otherwise double quot wrapper isn't required. Inside double quot, double quot is used to escape double quot. Suddenly the problem is complicated to something more than string splitting, however it can be simplified into a finite state machine with 4 states. States: 1. Ready for new field (initial state) 2. Field without double quot 3. Field with double quot 4. Escaping or end of double quot Transitions *Direction*|*Condition*|*Ac
